The model consists of a solar-like differential rotation, a magnetic diffusivity varied with depth, and three types of alpha-effects with different locations, i.e. the tachocline, the whole convective zone and the sub-surface. Some comparisons of the critical alpha-values of axisymmetric m=0 and longitude-dependent modes m=1,2,3 are presented to show the roles of the magnetic diffusivity in the problem of modes selection.
